More ram or a bigger hard drive means $$. If you want to save money, ockham's idea is your best bet. Or, If you have a graphics program like PhotoPaint or PhotoShop, you could try this... Load the pz3 and then try to figure out what parts could be split up into separate renders. (Watch especially for where shadows cross each other here). Then delete say, half the foreground objects and save the pz3 -- with a different name (!) Don't delete any lights or change anything else. Then reload the original pz3, delete the other half of the foreground objects and save with yet another name. Again, don't delete any lights or change anything else. Then load and render the two pz3's separately. Next, in your graphics program, load both resulting images. Split one in half and paste that half into its position in the other image. Combine the two and save. Just an idea...
